Perovskite solar cells have made remarkable progress in laboratory-scale efficiency, positioning them as a promising next-generation photovoltaic technology. However, their long-term operational stability under real-world conditions remains a critical barrier to commercial deployment. This study presents a three-year outdoor field investigation of a micro power station composed of 20 perovskite sub-modules (FACsPbI-based, each measuring 30 cm × 40 cm), deployed in subtropical eastern China and fabricated using scalable, industry-compatible processes. The system was continuously monitored over a three-year period to assess its long-term energy output and operational stability under real-world conditions. In parallel, we developed a spectral-accelerated ageing protocol using a tailored ultraviolet to blue-violet light spectrum, with enhanced intensity in the 390-455 nm range. This method enabled a UV dose of 60 kWh m at 65 °C to effectively replicate approximately two years of outdoor degradation. The excellent agreement between the UV-aged and field-aged performance validates this as a practical and predictive tool for evaluating the outdoor lifetime of perovskite modules. The sub-modules demonstrated outstanding durability, with only a 2.83% decline in power conversion efficiency after three years of continuous outdoor operation. These findings support the implementation of perovskite-specific reliability testing frameworks and align with emerging international standards such as IEC TS 63624-1, highlighting the importance of tailored UV protocols in preparing perovskite technologies for commercial deployment.
钙钛矿太阳能电池在实验室规模的效率方面取得了显著进展，使其成为一种有前途的下一代光伏技术。然而，它们在实际条件下的长期运行稳定性仍然是商业部署的关键障碍。本研究对一个由20个钙钛矿子模块（基于FACsPbI，每个尺寸为30 cm×40 cm）组成的微型电站进行了为期三年的户外实地调查，该电站部署在中国东部亚热带地区，采用可扩展的、与工业兼容的工艺制造。该系统在三年时间内持续监测，以评估其在实际条件下的长期能量输出和运行稳定性。同时，我们开发了一种光谱加速老化方案，使用定制的紫外到蓝紫光光谱，在390 - 455 nm范围内增强强度。该方法能够在65°C下实现60 kWh m的紫外线剂量，有效地模拟大约两年的户外降解。紫外线老化和实地老化性能之间的良好一致性验证了这是一种评估钙钛矿模块户外寿命的实用且具有预测性的工具。这些子模块表现出出色的耐久性，在连续三年户外运行后，功率转换效率仅下降了2.83%。这些发现支持实施针对钙钛矿的可靠性测试框架，并与IEC TS 63624 - 1等新兴国际标准保持一致，突出了定制紫外线方案在为钙钛矿技术商业部署做准备方面的重要性。
